Rewterz Threat Alert – WinPot Malware Turns ATM into a Slot Machine

February 25, 2020

Severity

High

Analysis Summary

WinPot ATM Malware has affected more than 120 ATM machines and the number of affected victims is growing. Jackpotting commonly refers to attacks where cybercriminals force an automated teller machine to spew out money. WinPot can make the “ATM game” a sure-fire win, which could explain the first part of the name. The software helps criminals pick and empty the ATM’s most lucrative cash-dispensing cassette.The slot machine’s windows display each cassette’s bill denomination and the number of bills inside the cassette. All the mule needs to do is select the cassette with the most money in it and press Spin. The Scan button can be used to recount the bills. WinPot’s creators also provided an emergency Stop button for helping the mule cut the payout short before raising suspicions.

Impact

  • ATM turns into slotting machine
